Description

Technical Field

[0001] The utility model relates to the technical field of resource exploration, in particular to a phosphate rock resource reserve drilling and exploration device. Background Art

[0002] Drilling and surveying of phosphate resources is a key link in the development of mineral resources, involving the precise positioning and reserve assessment of underground phosphate deposits. This process combines a variety of modern scientific and technological means, including geological exploration, drilling technology and geophysical exploration.

[0003] First of all, geological exploration is the basis for drilling and surveying phosphate resources and reserves. Through geological surveys, geological mapping, geological profile measurements and other means, we can understand the basic conditions of the mining area, such as geological structure, stratum lithology, ore body morphology and occurrence. This information provides an important reference for subsequent drilling work.

[0004] Next, drilling technology is a key means to obtain direct information about underground phosphate deposits. Drilling methods include core drilling and engineering drilling. Core drilling directly observes and analyzes the mineral composition, structural structure and mineral content of rocks by drilling underground rock samples, providing direct evidence for the assessment of phosphate reserves. Engineering drilling is mainly used to understand the physical and mechanical properties of underground soil layers, groundwater levels and other information, providing basic data for mine design and mining.

[0005] After drilling is completed, it is necessary to sample the rock at the drilling depth and then test the sample to determine the content of phosphate ore in the rock at that location. However, existing drilling and surveying equipment does not have a sampling function. The drilling equipment can only be moved away from the drilling position after drilling is completed, and then other equipment is used to sample the rock at the drilling depth, thereby increasing the use of equipment and reducing the efficiency of sampling after drilling. At the same time, during the sampling process, the sampling device is prone to rocks at other depths falling into the sampling device and mixing when taking out the rock sample at the predetermined location, thereby reducing the accuracy of the survey.

At the same time, during the sampling process, the sampling device is prone to rocks at other depths falling into the sampling device and mixing in the process of taking out the rock samples at the predetermined position, thereby reducing the accuracy of the survey.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4As shown, a phosphate resource reserve drilling and surveying device comprises a fixed frame 1, a driving assembly 2 is arranged inside the fixed frame 1, a hollow shaft 3 is arranged on the driving assembly 2, a drill bit 4 is arranged at the bottom of the hollow shaft 3, a cavity 401 connected to the hollow shaft 3 is opened inside the drill bit 4, a through groove 402 is opened at the bottom of the cavity 401, a slide rod 5 is slidably connected inside the cavity 401, the length of the slide rod 5 is greater than the diameter of the through groove 402, a connecting rod 501 is fixedly connected to the bottom of the slide rod 5, and the connecting rod 501 is fixedly connected to the bottom of the slide rod 5. A conical block 502 is fixedly connected to the bottom of the connecting rod 501. The diameter of the connecting rod 501 is smaller than the diameter of the through groove 402. The conical block 502 is squeezed and sealed against the through groove 402 during the drilling process to prevent rocks from entering the through groove 402 during the drilling process. A fan 6 is fixedly connected to the side wall of the fixed frame 1. An air inlet pipe 601 is fixedly connected to the air inlet end of the fan 6. The air inlet pipe 601 is connected to the top of the hollow shaft 3 through a rotating joint 602.

[0025] like Figure 1 As shown, the driving assembly 2 in the above-mentioned includes a screw rod 201, which is rotatably connected to the inside of the fixed frame 1, and a lifting motor 203 is fixedly connected to the top of the fixed frame 1. The output end of the lifting motor 203 is fixedly connected to one end of the screw rod 201, and a lifting plate 202 is threadedly connected to the outer wall of the screw rod 201. The two ends of the lifting plate 202 are against the inner walls of the fixed frame 1 on both sides. The hollow shaft 3 is rotatably connected to the lifting plate 202, and the bottom of the lifting plate 202 is fixedly connected to a driving motor 205. The output end of the driving motor 205 is transmission-connected to the hollow shaft 3 through a transmission belt 206. By starting the driving motor 205, the driving motor 205 drives the hollow shaft 3 and the drill bit 4 to rotate, and then starts the lifting motor 203. The lifting motor 203 drives the screw rod 201 to rotate, and the screw rod 201 drives the lifting plate 202 to move downward in a state of being limited by the inner wall of the fixed frame 1, and the lifting plate 202 drives the drill bit 4 at the bottom of the hollow shaft 3 to move downward in a rotating state, and then screws into the ground for drilling.

[0026] like Figure 1 As shown, there are two groups of screw rods 201, which are connected to each other through a transmission chain 204. The two groups of screw rods 201 are symmetrically arranged on both sides of the hollow shaft 3, and are threadedly connected to the lifting plate 202 through the two groups of screw rods 201, thereby driving the lifting plate 202 to move up and down, thereby improving the stability of the lifting plate 202 driving the drill bit 4 at the bottom of the hollow shaft 3 to drill.

[0027] like Figure 1 and Figure 3As shown, the bottom of the hollow shaft 3 is fixedly connected with a spiral joint 302, the outer wall of the spiral joint 302 is threadedly connected with a hollow connecting tube 301, and the drill bit 4 is arranged at the bottom of the hollow connecting tube 301. By adding one or more groups of hollow connecting tubes 301 between the hollow shaft 3 and the drill bit 4 for connection, the drilling body of the drill bit 4 can be increased, thereby improving the convenience of use.

[0028] like Figure 1 As shown, a collecting box 7 is provided on one side of the fixing frame 1, and a discharge pipe 603 is fixedly connected to the output end of the fan 6, and the outlet of the discharge pipe 603 is located on the upper side of the collecting box 7. The core samples extracted by the fan 6 are discharged into the collecting box 7 through the discharge pipe 603 for collection, thereby improving the convenience of collection.

[0029] like Figure 1 As shown, the side wall of the fixing frame 1 is fixedly connected with a filter plate 701, the filter plate 701 is attached to the top of the collecting box 7, the outlet of the discharge pipe 603 passes through the filter plate 701 and then delivers the extracted core sample into the collecting box 7. At this time, the top of the collecting box 7 is shielded by the filter plate 701, which can discharge the air while preventing the core sample from splashing out of the collecting box 7, thereby improving the stability of the collection.

[0030] like Figure 1 As shown, fixing pins 8 are provided on both sides of the fixing frame 1. After the fixing frame 1 is installed and placed, the fixing pins 8 are inserted into both sides of the fixing frame 1 to further fix the fixing frame 1, thereby improving the stability of the fixing frame 1 during operation.

[0031] The working principle of the utility model is as follows: the driving component 2 drives the hollow shaft 3 and the drill bit 4 to rotate and move downward to insert into the soil for drilling. When the drill bit 4 penetrates to a predetermined depth, the driving component 2 drives the drill bit 4 to move upward by a distance of 5-10CM. At this time, the conical block 502 at the bottom of the drill bit 4 pulls the connecting rod 501 and the sliding rod 5 downward by its own weight, so that the interior of the cavity 401 is connected with the space inside the borehole through the through groove 402. At this time, the driving component 2 is stopped, and then the fan 6 is started. The fan 6 extracts air through the air inlet pipe 601, thereby The rotary joint 602, the hollow shaft 3, the cavity 401 and the through groove 402 generate negative pressure suction inside the borehole, so as to suck out the core sample broken by the rotation of the drill bit 4 below the drill bit 4, and then suck it out by the fan 6 through the through groove 402, the cavity 401, the hollow shaft 3, the rotary joint 602 and the air inlet pipe 601 for collection, so that the core sample at the predetermined depth position can be quickly taken out, thereby improving the efficiency of material taking. At the same time, no additional equipment is required for extraction, and it is avoided that the core sample is mixed with the core sample at other positions inside the borehole during extraction, thereby improving the accuracy of taking out the sample at the predetermined depth.

[0032] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
